Chinese Herbal Medicines 2018;10(4):388-395
Objective: Crude Leonuri Fructus (CLF), the fruits of the Leonurus japonicus Houtt, and processed Leonuri Fructus (PLF) by stir-baking as the important Chinese herbal medicines, have been used in China and other Asian countries for thousands of years. The objective of this research is to reveal the difference between CLF and PLF. Methods: The sensory technologies of the colorimetry, sensitive and validated HPLC-ELSD and GC combined with flame ionization detector (GC-FID) were employed to discriminate CLF and its processed product PLF. The color parameters of the samples were determined by colorimetric instrument CR-410. Moreover, the content of stachydrine and six fatty acids were determined by HPLC and GC. Subsequently, analysis of variance (ANOVA), principal components analysis (PCA), hierarchical cluster analysis (HCA), and Kendall's correlation test were performed for data analysis. Results: The CLF and PLF were divided into two categories by PCA and HCA in terms of their component content and color. The results distinctly demonstrated significant changes in color and the content of indicative components between CLF and PLF. Conclusion: The study revealed that HPLC, GC, and colorimetric method in combination with chemometric method could be used as comprehensive quality evaluation for CLF and PLF.

Synovial sarcoma is a rare tumour found in soft tissue; it is a mesenchymal spindle cell tumour that is not related to the synovial membrane. This tumour has a low incidence, and the most frequent place of occurrence is the lower extremities in young adults. Synovial sarcoma of the head and neck accounts for 3%-5% of sarcomas in this anatomical region. The tumor in the nasal cavity is less than 1%. The treatment of choice for synovial sarcoma of the head and neck is complete surgical excision of the tumour mass followed by adjuvant radiotherapy.
